THE PHASE FOUR

RF THRUSTER

POWERFUL: Highest thrust-to-power ratio

NOVEL: Patented small-scale magnetic nozzle to direct thrust

SCALABLE: Fits the CubeSat form factor, can be clustered for larger satellite applications

HIGH VALUE: Attractive price for value delivered (highest thrust-to-power per unit mass)

COMPACT: Smallest plasma thruster commercially available

EFFICIENT: RF plasma heating allows for high electrical system efficiency and compact form factor

ENABLING PREVIOUSLY IMPOSSIBLE SPACE MISSIONS

The P4 Radio Frequency Thruster (RFT) is a new system designed for small satellites while being scalable to large satellite and even launch vehicle applications.  The RFT was inspired by technology developed at The University of Michigan and licensed exclusively to Phase Four for commercialization.

Phase Four has completed build and test of the initial prototype, has a space demonstration planned in early 2018, and is currently taking customer orders.
